The method of repairing boots and shoes with the aid of a paste as now successfully practised necessitates specially designed presses permitting to clamp fast the work-piece very securely and in such a manner that it is accessible on all sides and can resist the pressures to which it is subjected while the repair is being effected. As regards, for instance, the pasting on of soles there is required for this sort. of work a stationary support upon which the boot or shoe is to be shoved and which is provided with clamping bows, belts, and the like for holding a pressure-exerting or more precisely, pressure-transmitting cushion (termed press-cushion in the following onto: the sole lying upon the boot or shoe. A press of this design is, however, not suited for the pasting on of patches, toe-caps or leg parts and can be used only for one of these several pur poses. Owing thereto, there is, for instance, the

press cushion requisite for pressing on the substitute boot or shoe part to be pasted on arranged at a bow to which it can be attached, together with a threaded adjusting spindle, in several positions, but as said bow is not sufficiently resistible, the press cushion cannot be subjected to a sufficiently high pressure in the several positions to which it must be adjusted for the carrying out of the respective work.

Presses having a stationary base plate, and a cushion carrier firmly attached thereto and permitting of being tightened up together with the appertaining adjusting spindle, are likewise suited only for the subsequent pasting on of substitute boot or shoe parts or of heels. It has been suggested to make the last carrier turnable so as to render it possible to adjust the work-piece with respect to the member efiecting the pressure in such a manner that it is accessible on all sides, and it has, further, already been suggested to make said carrier also adjustable, or shiftable respectively; but constructions of this kind necessitate long jib arms which donot make it possible to exert a suificiently strong pressure during the pasting-on operation, except, the entire frame be extraordinarily clumsy, but a frame of such a type is not suited for small repair work, furthermore too expensive, too circumstantial and also too bulky.

The present invention relates to a simple, small-size boot and shoe pasting press for pasting on patches and for general repair-work which is distinguished by the features that the presscushion is guided on an arm turnably attached to the base plate of the press and being fixable parts of this specification) which is to be pressed I at said plate. If, besides, an exchangeable abutment member is provided at the base plate, the boot or shoe to be repaired can be clamped fast in any desired position with respect of the presscushion and to the abutment member and is accessible' on all sides, especially also at the leg, so as to permit the pasting-on of patches, as well. as of soles and heels. An especially important feature of this improved press is, furthermore, that it is extremely rigid and still in itself so that the place where a patch orthe like is to be pasted-on can be subjected to a pressure of any requisite magnitude and the repair can be of an excellent quality highly satisfying the wearer'o-f the respective boot or shoe.

The invention is illustrated diagrammatically and by way of example on the accompanying drawing in which Figure 1 is a vertical section through a boot and shoe pasting 'press designed according to this invention, with a boot to be repaired inserted, the section being seen in the direction from the toe portion of the heel. I

Figure 2 is a side-view of the parts shown in Fig. 1.

Figure 3 is a view similar to Fig. 2, but showing the boot in another position and the vertical bow (2) of Figs 1 and 2 being turned down into horizontal position; and Figure 4 is a view similar to Fig. 3, but showing the boot again in another position.

On the drawing, .i denotes a base-plate to which is hinged a bow 2 by meansof bolts 3. Although I have shown an actual U'-shaped bow comprising an arm on its right-hand side and an arm on its left-hand side; I wish it to be understood that, under circumstances, one arm maysuiiice, but I prefer the constructional form shown on account of its greater rigidity. The bow can be secured in its vertical position, as well as in its horizontal position, by means of pins or bolts 4 engaging suitably located bores, as shown in Figs. 2 and 3.

In the bow is guided a shiftable spindle 6, to the lower end of which the press cushion 9 is attached. A helical compressive spring 8 surrounding the upper end of said spindle tends to' hold the spindle with thepress cushion in lifted position, but these' parts can be fixed in any position therebelow by any suitable means, for instance a clamping device 5, 1 or any other suitable contrivance of known design. On the top of the spindle, above said spring, is a knob II, with the aid of which the press cushion can be depressed upon the boot or shoe portion where a patch is to be pasted on or any other repair is to be made, and thereafter the cushion is fixed in this position by means of said device 5, I or its equivalent. When the work has been finished, the device 5, T is released, whereupon the spring will lift the cushion off from the work-piece.

Also the press-cushion 9 can be of any desired design; it may, for instance, be completely stuffedout or may be filled with a liquid or a gas and may be equipped with a member permitting pumping up the cushion if necessary. As a rule, however, the cushion shall be completely closed and retain its filling permanently.

The cushion is connected with the spindle 6 by means of a plate 6* which is provided with a means for exerting an additional pressure upon the cushion after it has been depressed by the intermediary of the spindle and secured in that position by the clamping device 5, i. In the example shown said means consists of a plate 9* attached to the bottom surface of the plate 6 and being loosely hinged thereto at one end (9 whereas the other end is subject to the action of an eccentric 9 supported upon the plate 6 When the grip (shown in dotted lines in Fig. 1) pertaining to the eccentric is turned from its right-hand position (Fig. l) to its left-hand position, the eccentric proper will depress the plate S and exert thereby the additional pressure upon the press-cushion 9.

In operation, when a boot or shoe is to be repaired, the respective Work-piece is placed upon the base plate as, for instance, in Figs. 1 and 2, and the press-cushion is moved down upon it by means of the members H and t, and is pressed firmly against it, whereafter the cushion is fixed in this position by means of the clamping device 5, l, as already described. Now the additional plate 9* is depressed by means of the eccentric 9 so as to ultimately secure the press-cushion in its position on the work-piece.

In Figs. 1 and 2 is assumed that a toe-cap is to be pasted onto the boot l2, and it is for this reason that the how 2 and the spindle 6 are in their vertical position. In order to effect a repair for instance at the rear of the heel or at a side of the same the bow with the spindle are turned into horizontal position, as in Figs. 3 and 4, and in order to give the boot (or shoe) a firm hold also in any of these positionsor in a similar position, an abutment member it! (may be, several such members) can be attached to the base-plate and be secured thereon by means of a pin W engaging any of a plurality of bores i provided in said plate. In Fig. 2 the abutment member I is in its position of rest, viz. not engaged,

whereas it is engaged in Figs. 3 and 4 in two diiierent positions.

I claim:

1. In a boot and shoe pasting press, especially for patches and repairs, in combination, a stationary base-plate on which the boot or shoe to be pasted is placed, an arm turnably hinged to said plate, means adapted to adjust said arm to said plate in predetermined positions, a press cushion guided on said arm, means for adjusting and fixing said cushion on said arm in different positions, the hinge between said plate and said arm lying above the level of said plate, and substantially on a level with the boot or shoe to be pasted.

2. In a boot and shoe pasting press, especially for patches and repairs, in combination, a stationary baseplate, an arm turnably hinged to said plate, means adapted to adjust said arm to said plate in predetermined positions, a press cushion guided on said arm, means for adjusting and fixing said cushion on said arm in different positions, means for subjecting the plate with said cushion to a preliminary or initial pressure, and separate means for exerting a finishing or final pressure as an addition to the first-mentioned pressure are provided.
